Definitions

  • the invention relates to a method for reprofiling at least one tongue of a switch laid in a track.
  • Rails laid in a track are naturally subject to wear, which is mainly caused by the contact forces acting between the rails and the wheels of the rail vehicles moving thereon.
  • the undesired changes in the rail cross-section that occur as a result are subjected to a reprofiling process, either regularly or on an ad hoc basis, in order to extend the service life.
  • the reprofiling is carried out mainly with machining processes such as grinding, planing or milling, with these processing processes being carried out either on dismantled rails or by means of rail-guided processing vehicles on the laid track.
  • EP 1 820 902 A1 by the same applicant proposed a method for milling rail heads of track rails laid in a bed by means of a movable milling device.
  • the milling device comprises a rotary driven milling cutter head, which is stored in a chassis containing a milling cutter head drive.
  • the milling cutter head is guided vertically and/or laterally with guide means along the rail head to be machined, the milling cutter head having several sets of cutter head blades arranged one behind the other in the circumferential direction of the milling cutter head.
  • Each set of cutterhead blades reproduces the profile of the rail head to be machined in approximately circular partial arcs of different radii.
  • the target profile of rails can be restored in a short time in an efficient manner, but their use has only been possible on continuous track sections, while on track sections with interruptions in the rails, such as in the area switches or crossings, the reprofiling is often done with hand-held processing tools or smaller special devices, which means that the reprofiling of tracks in the area of switches or crossings still causes longer closure times due to a high proportion of manual work and thus longer-lasting obstacles to rail traffic with correspondingly high follow-up costs.
  • the object of the present invention was to overcome the disadvantages of the prior art and to provide a method for reprofiling at least one tongue that is easier to carry out and damage to the stock rail that interacts with it can be avoided.
  • the method is used for reprofiling at least one tongue of a switch installed in a rail track by means of at least one first processing unit held on a processing vehicle so that it can be adjusted relative thereto and having a first processing tool.
  • At least the following process steps are to be carried out or provided for in order to carry out the process:
  • the advantage of the method steps selected here is that the provision of at least one counter-holder, which is achieved in the area between the tongue to be machined and the respective rail section, namely the stock rail, transverse stabilization of the tongue for profile processing.
  • the processing forces introduced by the processing tool during profile processing are transmitted to the processing vehicle by the at least one counterholder.
  • a direct contact or a support of the respective tongue on the stock rail interacting with it is thus reliably avoided.
  • the spaced arrangement and the associated formation of the gap prevents unintentional machining or damage to the stock rail by the machining tool performing the profile machining on the tongue.
  • a procedure is advantageous in which that tongue to be reprofiled during profile processing on at least one threshold located below the same, if necessary with the interposition of a slide chair plate, resting on the at least one threshold is supported. In this way, a safer load transfer of the machining force can be made possible during profile machining.
  • a further advantageous procedure is characterized in that immediately following the first processing step using the first processing unit and its first processing tool, a further processing step is carried out using a further processing unit with its further processing tool on the tongue to be reprofiled. After major material removal, such as a milling process, fine machining can be carried out to improve or increase the surface quality.
  • a variant of the method is also advantageous in which the profile machining on that tongue to be reprofiled is carried out during the machining journey of the machining vehicle.
  • the respective processing unit is moved together with the processing vehicle during processing in the direction of the catcher extension of the rail track.
  • a vertical and/or transverse alignment of the processing unit can additionally be carried out.
  • Another procedure is characterized in that the profile processing is carried out on that tongue to be reprofiled with the processing vehicle stationary and the processing unit with its processing tool being displaced relative to the processing vehicle.
  • the respective processing unit can be adjusted relative thereto, guided by means of its own adjustment arrangements, when the processing vehicle is stationary along the tongue to be reprofiled. In this way, an even more precise and even tracking of the machining tool on the tongue to be machined can be made possible.
  • a procedure is advantageous in which, before the beginning of the machining steps of profile machining on that tongue to be reprofiled, first the rails forming the rail track are reprofiled, in particular their running surface is reprofiled.
  • the necessary removal of worn and/or damaged faulty rail material takes place in mutual coordination of stock rail and tongue rail with each other in the height direction. It may also be necessary to machine the tongue rail or the stock rail more in the vertical direction.
  • Another procedure is distinguished by the fact that the rails forming the rail track are reprofiled outside of the points.
  • a variant of the method is also advantageous in which at least individual rail sections of the rails are reprofiled within the switch, in particular the stock rail, the intermediate rail, the frog with the wing rail and, if necessary, the frog tip.
  • a further advantageous procedure is characterized in that the reprofiling of the rails and also the reprofiling of that tongue to be reprofiled is carried out with the same processing units. This means that the machine-technical requirement can be kept lower. Furthermore, the machine size of the processing vehicle can also be made smaller and therefore more cost-effective.
  • a variant of the method is also advantageous in which, for carrying out the reprofiling of that tongue to be reprofiled, the processing unit or the processing units are shifted from the respective rail to that tongue to be reprofiled. This can be carried out using separate guide and/or adjustment arrangements. The corresponding alignment for profile processing can be carried out using tactile sensors in order to be able to achieve correct reprofiling.
  • Another procedure is distinguished by the reprofiling of that tongue to be reprofiled and the reprofiling of the rails being carried out by means of processing tools which are designed differently from one another with regard to their working profile.

Abstract

L'invention concerne un procédé de reprofilage d'une lame (11, 12) d'un aiguillage (2) posé dans une voie ferrée (1) au moyen d'au moins un premier organe d'usinage (35) maintenu sur un véhicule d'usinage (34) et comprenant un outil d'usinage (33). Pour l'usinage de profilé, la lame (11, 12) à reprofiler est disposée à une certaine distance dans la direction transversale d'une contre-aiguille (9, 10) coopérant avec celle-ci par formation d'un espace (39). Un contre-support (40) qui est maintenu sur le véhicule d'usinage (34) est introduit dans l'espace (39), au cours de l'usinage de profilé, le véhicule d'usinage (34) étant guidé le long de la lame (11, 12) et cette dernière étant pressée par l'outil d'usinage (33) contre le contre-support (40) et s'appuyant sur celui-ci.
